“ In 2003, Wal-Mart spent $1.4 billion on its health insurance. This amounts to an employer contribution of around only $0.75 an hour per employee. This accounts for approximately a half-percent of Wal-Mart's $259 billion in sales in 2003. (Wal-Mart 5500 Filings, Wal-Mart Annual Report). “
对于这道题,我是选了C, 但是看了大家的讨论后,确定答案应该是D。
C的致命伤在于没有说清楚: "Regular syrup does not sell for a higher price per unit than low-calorie syrup" 翻译为“普通糖浆的价格不比低糖糖浆高“。 可理解为“普通糖浆的价格等于或低于低糖糖浆的价格“。
如果两者价格相等,起不到weaken的作用。
如果普通糖浆的价格低于低糖糖浆的价格, 我们需要make a future assumption (普通糖浆的销售量不足以弥补它的低价格对普通糖浆销售额的负面冲击) to weaken。
